What is JavaScript?
This programming language is embedded within HTML pages and
manipulates the attributes of those pages. JavaScript differs from CGI in that
the former generally does not require the user to reload a page in order to
execute the program. However, JavaScript has a number of disadvantages: For one,
the set of functions that you have to work with is quite limited compared to
most programming languages used for CGI programming. In addition, various
browsers have implemented different versions of JavaScript, resulting in
programs running fine in one browser yet with great difficulty (or not at all)
in another. Some browsers -- notably WebTV -- cannot handle JavaScript at all.
Still, JavaScript is quite useful for building dynamic Web pages, as long as you
write a script that will prove compatible with most browsers. Better yet, you
can borrow a script where the work's already been done for you! |
